HOLDERS FOR PROTECTING STICKS OF FASTY MATERIALS Filed July 10, 1968 United States Patent Int. Cl. B43k 23/00 US. Cl. 40178 Claims ABSTRACT OF THE DISCLOSURE A holder for a stick of pasty materials such as cosmetics, make-up and the like having a pair of relatively rotatable coaxial sleeves having portions in confronting rubbing relationship, one of said portions defining a groove-like reservoir for containing a sticky substance which acts to brake rotation of the other of said portions with respect to the first portion.

This invention concerns holders for protecting sticks of pasty materials such as make-up, pomades. cosmetics, pharmaceutical or veterinary products and the like, of the type comprising two coaxial sleeves which can turn one relatively to the other and a stick support or godet for a stick which is movable in the inner sleeve and which carries a lug extending through a slot in the inner sleeve and also engaged in a slot in the outer sleeve, one of these two slots being longitudinal and the other helicoidal, the end of said holder being closed by a removable cover.

In holders of the kind in question it is desirable to avoid the outer sleeve turning on the inner sleeve due to vibration so that the stick support would approach the cover, an occurrence which would risk bringing the end of the stick into contact with the bottom of the cover against which it would be undesirably deformed.

To this end, according to the invention a sticky substance fills a groove forming a reservoir in one of the mutually rubbing faces of the two sleeves.

The invention will be better understood by reading the following description and examining the accompanying drawings which show by way of example several embodiments of the invention.

In these drawings:

FIGURE 1 shows in longitudinal section a complete assembled holder of a first embodiment of this invention;

FIGURE 2 shows in longitudinal section to a larger 0 scale one end of the outer sleeve alone, and

FIGURE 3 shows a modification of FIGURE 2.

The holder for a stick of pasty material such as makeup, pomade, cosmetic, pharmaceutical or veterinary products or the like shown in FIGURE 1 comprises in a conventional manner a stick support or godet 21 which carries the stick of pasty 'material 22 and which is mounted for longitudinal sliding movement in an inner sleeve 23. To this end the stick support 21 has projecting from its outer cylindrical surface two diametrically opposed lugs, such as 25, which can slide in two longitudinal slots 27, 28, respectively, formed in the cylindrical wall of the inner sleeve 23. On this inner sleeve 23 can turn an outer sleeve 31 (see also FIGURE 2) retained axially by two shoulders 32, 33 on the inner sleeve. In the inner face of the cylindrical wall of the outer sleeve 31 are formed two diametrically opposed helicoidal slots 35, 36 in which are engaged the ends of the lugs 25 on the sliding godet 21.

A metallic reinforcing tube 39 is fitted by force on the "ice outer sleeve 31. One end of tube 39 has an end 41 defining an opening 42 for the passage of the stick 22, the opening being covered by a conventional cover which, for clarity of illustration, has not been shown.

In order that, due to the effect of vibration, the two sleeves should not turn one relatively to the other while the holder is closed, so that the end of the stick 22 does not risk coming into contact with the bottom of the cover, an annular groove 91 is formed in the inner cylindrical face of a portion 44 of the outer sleeve 31, which face is in contact with a complementary cylindrical surface 45 of the inner sleeve. Groove 91 is filled with a sticky substance which brakes the relative rotational movement of the two sleeves when surface 45 is moved via knurled handle 43 with respect to outer sleeve 31.

In FIGURE 3 a modification is shown in which the sticky substance is disposed in separate hollows 93, 94, for example in place of it being found in a continuous annular groove.

As a sticky substance one can for example use a pressure-sensitive adhesive such as that sold under the reference F51 by the company called: Minnesota de France or other suitable glue.

The continuous or discontinuous annular grooves 0r hollows can be formed in the cylindrical surface of a confronting part of the inner sleeve in place of being formed in the bore of the outer sleeve.

The sticky substance instead of being found in the grooves could also fill simple isolated hollows formed in at least one of the cylindrical mutually rubbing faces of the two sleeves.

What is claimed is:

1. In a holder for a stick of pasty material having an opening at one end and adapted to be covered when not in use, comprising two coaxial cylindrical sleeves which can turn one relatively to the other and a support membet for supporting the stick which is movable axially within the inner sleeve and which carries a lug extending through a slot in the inner sleeve and into a slot in the outer sleeve, one of said slots being longitudinal and the other helicoidal, said sleeves being in rubbing engagement with each other along at least part of their length, the improvement comprising one of said sleeves defining a groove means confronting the other of said sleeves in the region of said rubbing engagement, and a sticky substance in said groove means which acts against said other sleeve to brake relative rotational movement of said sleeves with respect to each other.

2. A holder according to claim 1 in which said groove means is a continuous annular groove.

3. A holder according to claim 1 in which said groove means comprises a plurality of grooves each filled with said sticky substance, said grooves being disposed in an annular arrangement.

4. A holder according to claim 1 in which said groove means are in said inner sleeve.

5. A holder according to claim 1 in which said groove means are in said outer sleeve.
